Description

Claim 1. A machining center for machining vertical edges on a stack (9) of plate-shaped blanks (10), which machining center comprises a support (11) for supporting the stack (9) and a plurality of machining devices (1,2, 3,4; 15,17), each of which is arranged to be brought in and away from the stack (9), characterized in that the support (11) is adapted to rotate the stack (9) about a vertical axis (13) and the processing devices (1,2,3,4; 15, 17) arranged to be displaced in a fixed path between an outermost position away from the stack (9) and an inner one position, against or near the vertical edges of the stack (9), regardless of the angular rotation of the stack (9). Processing center according to claim 1, characterized in that each of the processing devices (1,2,3,4; 15,17) is mounted on a carriage (5) which can be displaced radially towards and away from the stack (9). ) along a console (6). Processing center according to claim 1 or 2, characterized in that the processing devices comprise at least one abrasive drum (2,3) arranged rotatably about a vertical axis. Processing center according to claim 3, characterized in that the grinding drum (2,3) is provided with a flexible grinding material. Processing center according to claim 3 or 4, characterized in that precisely two abrasive drums (2,3) are provided which are arranged for rotation in opposite directions. Processing center according to any of claims 3-5, characterized in that measuring means are provided for scanning the peripheral geometry of the stack (9) and control means are provided for automatically moving the processing devices (1,2,3 , 4; 15.17) towards and away from the stack (9), depending on the scanned geometry and the rotation of the stack (9). Processing center according to claim 6, characterized in that the measuring means comprise a meter wheel (1) mounted on a carriage (5) which can be radially displaced towards and away from the stack (9). Processing center according to any one of claims 3-7, characterized in that further means for removing abrasive dust from the vertical edges of the stack (9) are provided. Processing center according to claim 8, characterized in that the abrasive dust removal means comprise a blower (4) mounted on one on a carriage (5) which can be radially displaced towards and away from the stack (9). Processing center according to claim 8, characterized in that the means for removing abrasive dust comprise a rotary brush rotating about a vertical axis mounted on a slide that can be displaced radially towards and away from the stack. . Processing center according to any one of claims 2-10, characterized in that the processing devices comprise a paint or varnish application device (15). Processing center according to claim 11, characterized in that a curing device (17) is further provided with curing agents for the paint or the varnish. Processing center according to claim 12, characterized in that the curing agents are UV lamps (18). Method for machining vertical edges on a stack (9) of plate-shaped blanks (10) by a plurality of machining devices (1,2,3,4 / 15,17) which are successively brought into contact with the stack (9). ) vertical edges and machining these along their entire circumference, characterized in that the stack (9) is rotated about a vertical axis (13) and the machining devices (1,2,3, 4 / 15,17) are displaced in a fixed web for machining the vertical edges of the stack (9). Method according to claim 14, characterized in that the processing devices (1,2,3,4 / 15,17) are displaced radially towards the stack (9). Method according to claim 15, characterized in that the vertical edges of the stack (9) are abraded in the following steps: - a metering wheel (1) is displaced radially for abutment against the periphery of the stack (9), the stack (9) is rotated one turn while its peripheral geometry is recorded, the metering wheel (1) is displaced radially away from the stack (9), - a first grinding drum (2) rotating in a first direction about a vertical axis is displaced radially to abut the vertical edges of the stack (9) while the stack (9) rotates one turn, the first grinding drum (2) is displaced radially away from the stack (9), - another grinding drum (3) rotating in a different direction about a vertical axis is displaced radially to one another. ¬ place against the vertical edges of the stack (9) while the stack (9) rotates one turn, the other abrasive drum (3) is displaced radially away from the stack (9), - a blower (4) or a rotating brush is displaced radially towards the vertical edges of the stack (9) while the stack (9) rotates one turn, blown the guide (4) or brush is displaced radially away from the stack (9).
